Lester blogged about his experience playing with The Roots, revealing that he was nervous, didn't know what they'd be playing two hours before taping and that he'd never taken a bass lesson before. Yes, the man is so smooth we had no clue he hasn't been playing his whole life.

"I am grateful to The Roots and Jimmy Fallon for helping to fulfill my dream," Lester wrote, "and will now happily return to my other dream job in the newsroom."

The anchors were impressed with his "Tonight" jam sesh. "He's already like one of the coolest guys who works here, but this just takes it to a whole another level," Savannah said. "Can we have your autograph?!"

Natalie joked, “He’s not going to talk to any of us now.”

Lester shared his response with TODAY.com.

"Of course I'll talk to you guys! Still the same old Lester although I am following up on Jimmy's advice to change the name of Dateline to Bassline NBC."
